The following steps can be used to determine the maximum mixing height for a day from a temperature profile:

Plot the temperature profile, if needed.

Plot the maximum surface temperature for the day on the graph for morning temperature profile.

Draw a dry adiabatic line (-1^oC/100m) from the point of maximum surface temperature to the point where it interests the morning temperature profile.

Read the corresponding height above ground at the point of intersection obtained in step 2. This is the maximum mixing height for the day.

Problem: Find the maximum mixing height for the day shown in the figure given below. The maximum surface temperature for the day was 22^oC.
